Released Subject to Change INTRODUCTION TheRiotFamilyofUltrasonicLevelSensors,(ProductFamily10000)wasdesignedtoprovideaccurate and costeffective remote monitoring of levels in various tanks, storage bins, and silos.

1. Sensors attributes:
a. Different products in the family use different Ultrasonic sensors with a variety of i. FrequencyMultiplefrequenciesareusedforvarioussonicqualities.Ingeneral, lowerfrequencysensors(longerwavelength)areusedforlongerdistances,and shorter for shorter. Also, shorter frequency sensors have shorter minimum distanceandtendtobemoreusefulforsmallertanks.Lastly,shorterfrequency sensors tend to be more power efficient and are more suitable for very long battery life in field applications. A given device has a fixed frequency due to optimizationoftheactualsignalingelement. ii. Material our standard sensors use an aluminum housing. This is sonically efficient and very low cost. We also use other materials (Kynar, etc.) for applicationswhereexposuretoreactivechemicalsisprevalent. iii. FrequencyandMaterialcanbespecifiedattimeoforder. b. SensorProcessingalldataisprocessedonboard.Theinternaldevicesincludeanalog anddigitalfiltering,signalrecognition,andtimedistancecalculationwithtemperature error correction. The data delivered to the user is in distance units as defined (i.e. inchesorcentimeters.) Physical Interface to the Transducer Data and commands can be sent to the transducer via wired or wireless means. A standard transducer has a Blue Tooth Low Energy (BTLE) interface built in.
